72b3ce7ac6 From Tugkan Calapoglu, "we started to have problems with textures after a recent svn update. I 
was able to follow the problem until following addition to Texture.cpp:

// GLES doesn't cope with internal formats of 1,2,3 and 4 so map them to
the appropriate equivilants.

if (_internalFormat==1) _internalFormat = GL_ALPHA;
if (_internalFormat==2) _internalFormat = GL_LUMINANCE_ALPHA;
if (_internalFormat==3) _internalFormat = GL_RGB;
if (_internalFormat==4) _internalFormat = GL_RGBA;


The problem is that internal format "1" corresponds to GL_LUMINANCE, not
GL_ALPHA. I double checked this from the Red Book. Fixed version is
attached to the email."

c481f022e9 From Wojciech Lewandowski, "Building on earlier Paul's submission "[osg-users] Main branch MSFBO support change", I have added implicit buffer mask variables to DisplaySettings for setting global defaults for Camera FBOs. These mask variables are named after variables in Camera class. In Paul's submission they were named _renderBufferMask & _resolveBufferMask but I renamed them to _implicitBufferAttachmentRenderMask & _implicitBufferAttachmentResolveMask. DisplaySettings implementation includes reading of environment vars and command line options. Setters and getters follow typical OSG naming convention. I also updated names of ImplictBufferAttachment enum bits to match changed naming scheme. 
DisplaySettings now define COLOR and DEPTH as defaults for implicit buffers. Consequently Camera by default uses the same defaults through USE_DISPLAY_SETTINGS_MASK. However, particular Camera mask can be easily overriden through Camera::setImplicitBufferAttachmentMask method. I hope, that in this way we can have global control over implicit buffer defaults, and we can still retain fine grained control at Camera level.

I have also replaced original unsigned ints used to store masks to signed ints because complier resolves enums as signed integer (I got a number of warnings with unsigned int)."

2a0497e2c1 From Pau Garcia i Quiles, "On Linux/Unix, when you change the system time (for instance, using 
settimeofday), OSG animations will freeze your application because
osg::Timer uses gettimeofday internally on non-Win32 platforms. This
is wrong and should be replace with times(2) or clock_gettime(2).

The attached patch fixes the issue in a binary-compatible way by using
clock_gettime when it's available, and falling back to gettimeofday
when it's not."
